WHEEL PLOW Patented July 4,1876,

UNITED STATES WILLIAM EVANS, OF MOLINE, ILLINOIS, ASSIGNOR TO THE MOLINE PLOW COMPANY, OF SAME PLACE.

IMPROVEMENT IN WHEEL-PLOWS.

Specification forming part of Letters Patent No. I 79,5 15, dated July 4, 1876; application filed April 15, 1876.

To all whom it may concern Be it .known that I, WILLIAM EVANS, of Moline, in the county of Rock Island and State of Illinois, have invented certain Improvements in Wheel-Flows, of which the following is a specification My invention consists in a novel construction of sulky plows, whereby the plow may be "more readily raised and lowered, and more perfectly adjusted, than in those now in use.

In the drawings, Figure 1 represents a top or plan view of my improved device; Fig. 2,

a side view of the same, having one of the wheels removed, to show more clearly the loca-' tion of the parts 5 and Fig. 3, a detached view of the clamp or coupling by which the plowbeam is attached to its shaft.

In the drawings, A represents the frame of the machine, which, as shown in Fig. 2, consists of avertioal or upright portion and a horizontal portion, extending forward from the top of the same, the two portions being stifl'ened by brace-rods g, running from one to.

the other, as shown. On this frame A are mounted two transverse crank-shafts, E and F, the former working iirbearin gs located at or near the lower part of the vertical portion of the frame A, and the latter in similar bear-.

ings on the horizontal portion of said frame, as shown. D is the plow-beam, which is attached to the crank-shaft E near its rear end by means of a clamp or coupling, G, which is shown detached and enlarged in Fig. 3. This clamp G is composed of a plate of metal, j, and two yolies, It, said yokes passing around the crank-shaft E until theycome in contact shown in Figs. 1 and 3, to which it is securely attached by the plate m, which passes over the beam, and is drawn down upon the same by means of nuts on the bolt-rods i t. The forward end of the beam D is attached to the forward crank-shaft F by means of a coupling, f, which is made to swing loosely on the said shaft, and is provided with a joint, 0, as shown in Fig. 2, which permits a lateral or sidewise movement of the forward end of the plowbeam. The crank-shafts E and F are connected with each other by means of a chain or similar flexible connection, S, which passes upward from the shaft E over a pulley, n, thence downward under a pulley, 0, and, finally, upward, and connects with the shaft F, as shown. To one end of the crank-shaft F is firmly attached a locking hand-lever, L, which looks into notches in a segmental rack, I. It will be readily observed that by elevating the hand-lever L, it being rigidly attached to the shaft F, said shaft must also be elevated, and that, as the plow-beam is attached at its forward end to the shaft F, the forward end of the beam will be elevated likewise. Now, as the chain S is attached to both the crankshafts E and F, it follows that when the lever L is raised, carrying with it the shaft F, the chain S is carried forward and upward from under the pulley 0, and down over the pulley n, thus drawing upward on the rear end of the plow-beam D, to which,.as before stated. the

chain is attached. It will thus be seen that when the lever L is elevated, the front and rear ends of the plow-beam D are elevated simultaneously. As shown in Fig.2,the coupling f, by which the forward end of the plowbeam D is attached to the crank-shaft F, is

provided with several holes, in order that the end of the beam may be elevated or depressed without reference to the rear end, in order to change the angle at which the point of the plow enters the ground, or for any other purpose that may be necessary.

The team is attached to the front end of the plow-beam, as usual, while the tongue is guided by the neck-yoke.

Each of the wheels is mounted on separate crank-shafts, which are adjusted and locked met.

in any desired position by means of levers and and n and the chain S, or its equivalent, all

segments, in a manner well known, whereby arranged to operate substantially as and for either wheel may be raised or lowered at will. the purpose set forth.

Having thus described my invention, what WILLIAM EVANS. 1 claim is-- l/Vitnesses:

The combination, in a snlky-plow, of the JOHN WV. GOOD,

two crank-shafts, E and F, with the pulleys 0 R. K. SWAN.
